Calibration of Horizontal Acoustic Doppler Current Profiler by three dimensional CFD simulations
(Journal article; Peer reviewed, 2015)This study presents a calibration method of horizontal acoustic Doppler current profilers (H-ADCP), based on 3D Computational Fluid Dynamics (CFD) simulations. Rigidly mounted H-ACCPs are currently used to continuously ... -
CFD modeling as part of a hybrid modeling case study for a gauging station with challenging hydraulics
(Journal article; Peer reviewed, 2019)Estimates of peak flood discharges are most often based on stage measurements, and the discharge is determined indirectly from the extrapolation of a rating-curve. It is possible to improve the extrapolation of the ... -
Energy transfer due to shoaling and decomposition of breaking and non-breaking waves over a submerged bar
(Journal article; Peer reviewed, 2017)Wave propagation over a submerged bar is simulated using the open source CFD model REEF3D with various incident wave heights to study shoaling, wave breaking features and the process of wave decomposition into higher ... -
Evaluating Wave Forces on Groups of Three and Nine Cylinders using a 3D Numerical Wave Tank
(Journal article; Peer reviewed, 2015)The evaluation of the complex wave regime due to wave interaction with a large group of cylinders placed in proximity requires an efficient and accurate numerical model. This paper presents the application of a two-phase ... -
Finding Free Surface of Supercritical Flows - Numerical Investigation
(Journal article; Peer reviewed, 2012)A three-dimensional numerical model (STAR-CCM+) has been used to compute the free surface for different cases with supercritical flow. The program solves the Navier-Stokes equations on an unstructured hexahedral grid using ... -
Multiple solutions of the Navier-Stokes equations computing water flow in sand traps
(Journal article; Peer reviewed, 2019)Two cases are presented wherein the main flow pattern in sand traps changes considerably as a function of discretization scheme, grid resolution and turbulence model. Both cases involve channel flows directed into a desilting ... -
Numerical Modeling of Flow Over Trapezoidal Broad-Crested Weir
(Journal article; Peer reviewed, 2011)Two computational fluid dynamics (CFD) codes, Flow-3D and SSIIM 2, have been used to calculate the water flow over a trapezoidal broad-crested weir. The two programs apply different algorithms for making the grid and ... -
Three-Dimensional Rans Modeling of Flow Around Circular Piers using Nested Grids
(Journal article; Peer reviewed, 2012)The paper introduces a three-dimensional numerical model that solves the Reynolds Averaged Navier-Stokes (RANS) equations on a curvilinear grid system using a novel nested grid approach. The main benefit of the model is ...
